The both ends of axle, the liquid accumulator include a welding bellows, shell and two end cap, and liquid accumulator can be by spiral case
Pressure is led in shielding pump motor, is realized that pressure at both sides is consistent, is avoided impurity from entering in pressure transfer device, the bearing block
It is connected by pipeline with one of end cap, another end cap is connected by pipeline with one end of the filter, the mistake
The other end of filter is connected by pipeline with spiral case, and filter can filter out impurity, prevents impurity from causing liquid accumulator to grind
Damage, the sealing ring are arranged between impeller and advancing slip dynamic bearing, and motor shaft is provided with perforate in the radial direction, and the perforate is with before
Cavity between sliding bearing and sealing ring is connected, and one end closing that the motor shaft is connected with impeller, the other end is hollow
Structure, and be in axial direction connected with the perforate.
Further, an accessory impeller is set on the motor shaft, the accessory impeller after described sliding bearing and
Between the rotor, accessory impeller can be flowed with liquid in drive motor, make bearing lubrication.
Further, the liquid energy accumulator housing is made up of transparent resin material, can be directly observed interior welds
Corrugated tube end position, so that it is determined that whether requiring supplementation with pure water on the inside of motor.
Further, the sealing ring includes rotary packing ring and stationary seal ring, and the rotary packing ring is fixed on axle, described
Stationary seal ring is fixed on motor case, and double sealing structure makes the more difficult entrance of impurity.
Beneficial effect：
1st, the pressure of spiral case can be led in shielding pump motor by liquid accumulator, realized that pressure at both sides is consistent, avoided miscellaneous
Matter is entered in pressure transfer device；
2nd, filter can filter out impurity, prevent impurity from causing liquid accumulator to wear；
The 3rd, one accessory impeller is set on motor shaft, sliding bearing lubricating in motor can be made；
4th, liquid energy accumulator housing is made up of transparent resin material, is easy to observe；
5th, sealing ring includes rotary packing ring and stationary seal ring, and dual-seal can make impurity is more difficult to enter in motor.
Brief description of the drawings
Fig. 1 is sewage disposal shielded electric pump section of structure.
Embodiment
Further explanation is done to the utility model below in conjunction with the accompanying drawings.
A kind of sewage disposal shielded electric pump as shown in Figure 1, including motor, bearing block 1, impeller 2, spiral case 3, front slide
Bearing 4, rear sliding bearing 5, liquid accumulator 6, filter 7 and sealing ring 8, motor include rotor 9, stator 10, motor shaft 11
With motor case 12, bearing block 1 is arranged on motor one end, and advancing slip dynamic bearing 4 and rear sliding bearing 5 are separately positioned on motor shaft 11
Both ends, liquid accumulator 6 includes a welding bellows 13, shell and two end cap, and bearing block 1 passes through pipeline and one of them
End cap is connected, and another end cap is connected by pipeline with one end of filter 7, and the other end of filter 7 passes through pipeline and snail
Shell 3 is connected, and sealing ring 8 is arranged between impeller 2 and advancing slip dynamic bearing 4, and motor shaft is provided with perforate in the radial direction, perforate with
Cavity between advancing slip dynamic bearing 4 and sealing ring 8 is connected, one end closing that motor shaft 11 is connected with impeller 2, and the other end is
Hollow-core construction, and be in axial direction connected with perforate.Pressure is consistently higher than pump intake volute pressure, liquid accumulator in motor
6 can be led to the pressure of spiral case 3 in shielding pump motor that welding bellows 13 is extremely soft, and bellows external and internal pressure is inconsistent
When, it is possible to achieve Automatic-drawing or compression, so as to realize that pressure at both sides is consistent, while in order to avoid impurity enters pressure transmission
In device；The shell of liquid accumulator can be process using transparent resin material, can be directly observed interior welds ripple
Line tube end position, so that it is determined that whether requiring supplementation with pure water on the inside of motor；Filter 7 can filter out impurity, prevent impurity
Liquid accumulator is caused to wear.Sealing ring 8 is arranged between impeller 2 and advancing slip dynamic bearing 4.
